Sleep disorders...alpha wave intrusion

I have lost my ability to have normal sleep. I can be up all night, go to sleep at dawn, or sometime before noon, and sleep until late at night, eat and go back to bed for 10-12 hours... My sleep is so unreliable it is difficult to even make appointments!

Here is what Harvard has to say, we would be under the musculoskelatal.

They refer to us having 'alpha-delta' sleep, or alpha wave intrusion, common in fibromyalgia patients.
